Westchester Announces Successful Completion and Testing of Initial Manitoba Well

TORONTO, ONTARIO--(CCNMatthews - Aug. 17, 2005) - Westchester Resources Inc. (TSX VENTURE:WSR) -

- 16-10 well tests 332 barrels of oil per day

- Completes drilling of second well and retains rig for a third well

- Increases land position in Manitoba

Westchester Resources Inc. (TSX VENTURE:WSR) today announced that it has been informed by its operator that testing of the first well in the Daley Field in Manitoba is complete. The 16 -10 well (located on the 16-10-009-28W1M lease) was drilled to measured depth of approximately 1600 meters. The horizontal leg was drilled in the Middle Daly section of the Lodgepole formation. The well was swab tested and encountered an initial production rate of 332 barrels of oil per day. Gas rates were minimal. The well will be temporarily shut-in pending the culmination of the immediate drilling program and the construction of the surface gathering facilities.

Drilling operations on the second well, the 10 -30 well, located on the 10 - 30 - 009 - 28W1M lease have been completed. Completion and testing of the 10-30 well will begin later in the week. The drilling rig will be moved to the 02/16-10 -14- 11- 9-28W1M lease to drill an additional horizontal well near the 16-10 well site.

The wells utilized horizontal drilling techniques to explore three potential zones: the Middle Daly Member and the Cruickshank Crinoidal Member in the Lodgepole formation and the underlying Bakken formation. Horizontal drilling has been used successfully in these type structures to enhance production and recovery rates. The well locations are within an area that has established production.

Westchester also announced that two additional leases in the Daley Field totaling 440 acres have been acquired through a Crown Land sale. With the addition of the two new leases, Westchester now holds a 50 percent interest in a total of 7 leases totaling approximately 2200 acres in the area. Consulting geologists and engineers estimate that approximately 25 additional drill targets are contained within the acreage.

Westchester owns a 50 percent working interest in each well through its Joint Venture Agreement with Aspen Group Resources Corporation (TSX:ASR). Aspen is the operator on each well.
